a. relaying a signal from a growth factor receptor even in the absence of the growth factor
b. dna repair
c. anchorage dependence and cell division
d. density dependent inhibition or cell-cell recognition

Answer is A.

Explanation:

The regulation of cell division and proliferation are the activities of a group of protein known as Ras protein , which are found near cell membranes. And abnormal Ras protein bring about uncontrolled cell division resulting in tumors development.

C. anchorage dependence and cell division

Explanation:

The cancer-causing forms of the Ras protein are involved in anchorage dependence and cell division.

the correct answer is - d. china has a large and growing population.

the fact that china has a large (the biggest) population, and it is still growing, doesn't hinder the agriculture production in the country. in fact, it can for increased production in the agriculture, since there's more labor force, as well the sheer mass of people produces lots of scientists that come up with new inventions as to how to improve this sector. nice example is the inner mongolia region in china, in general dominated by the gobi desert, but few scientist came up with a nice idea as to how to make the region productive by using plants that are very resistant to droughts, so lots of people have been employed, and the region is becoming greener and greener each year, and the production of food in this region is also increasing.
